To all whom it m'ay concern:

Be it known that I, MORLEY PUNsnoN. REYNOLDS, a citizen of the United States,

and resident of Clevelandfln the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in"Hatch- Ventilators'and Ice-Plugs;and I do hereby declare the following to be a full, clear, and

eXact description thereof. 1 My invention pertains to hatch ventilators and ice plugs, particularly for use-in connec' tion with railroad refrigerator cars, produce cars or the like; and the invention relates especially to combined hatch'ventilators and ice plugs for such cars. It is anobjectof my inventionto provide a hatch ventilator for produce cars and the like, which will permit the admission to the car of a greater volume of air than has been the case with the ventilators commonly in use. It is a further object of my invention to provide 'a' hatch ventilatorwhich, while admitting air to the car'in large quantity, will efiectually' exclude'cinders or other dirt. It is another object of my invention to provide a hatch ventilator which,'while performing its ventilating functions properly, will effectively exclude rain and other moisture, from the interior of the car. Another object ofmy invention lies in the provision of a combinedventilator and ice-plug in whichthe ventilator and ice-plug may be openedtogether,

or the ice-plug may be opened alone,at will.

It is still another object ofmy invention to provide a combined ventilator and ice-plug of a strong, simple and economical construction, which will be convenient in useand unlikely to get out of order and theparts of which may readily be repairedin case of ac cident, andto improve upon hatch-ventilator and ice-plug construct-ionsgenerally. And other and further objects of the invention,

will appear'from the following specification taken 111 connection with the claims'an will be understood, however, that my inven tion may take other forms, and that alterations may be made in the particular form which; has been described and shown, with out exceeding the scope of the invent-ion, as

defined in the appended claims.

'In the drawings! i Figure 1 is a'sectional side elevation ofthe ventilator, showing, in full 'lines,fthe

ventilator and ice-plug closed, and, in broken lines, the, ice-plug open, the section being taken on the line 22 of 2,looking in the direction of the arrows} i Fig. 2 is asection taken on'theline 3-.-3of

Fig. 1, looking'in the direction of the ar- 'rowsyr Fig. 3 1s a partial end view'of a car havlng hatch ventilators constructed inaccordance with my invention applied thereto.

;=L'1 e characters of reference indicate like parts throughout the following specification and'the several figures of the accompanying drawings. 1

Referring now-to the drawings, 10 desig nates a coaming, preferably of woodfof rectangular shape, which 1s built on the carroof around each of the hatch-openings, of Y which latter, in the form illustrated, there are four, one at each side of each end of the car. Y V

Y The coaming 10 is'provided with a lining 11 having therein a downwardly and in-- wardly tapered opening 12 communicating I Secured to the thereof. Betweenthe ledge 13 and the seatportion 15, the cap isformed with an uptherearound.-

, lhe ventilator includes a-box-shaped-hood 17;, the open lower side of which rests upon" 'wardly-extending bead entending entirely V the cap-ledge 13, outside and surroundingf the bead l6. 'Embracing'the outer or rear end and twosides' of the'hood 17, is a strap 18 which terminates incars or lugs'19;

These lugs are hingedly mounted on atrans-Y verse rod 20, which latter is-carried by two pairs'of brackets 21*secure'd to the cap flange V which facesjaway from the end of'thejcar.-- Thus the ventilator hood maybe swung,

1 1 at the frontend thereof, i. e, the endaboutthe rod 20, upand away from, the

hatchway, and, to facilitate this, the hood is provided with a lifting "handle22 at the top thereof; At the end of the device oppow site to the rod 20, the strap 18 is provided at its center with a staple 23, and the capfiange 1 1 has hinged thereto a hasp 24 which may be passed over the staple 23. \Vhen the ventilator hood is closed down with the hasp in place on the staple, a padlock may be passed through the latter to lock the ventilator initsclosed condition, or a carseal or the like may be employed for the' same purpose.

The front end of the ventilator hood- 5. 6., the end facing away from the adjacent end of the caris open, and has secured therein a screen 25, the latter being held in place by means of suitable clamping frames extending around the same. This screen prevents the entrance of dirt, cinders, and the like into the car. Secured to the side walls of the hood, and extending transversely there-across immediately behind the screen 25, are a series of superposed, downwardly and rearwardly inclined baflie plates 26, the lower ones of which are of less width than the upper ones. Extending from immediately behind the screen 25, at the lower'part thereof to a point near the middle of the hood, is a large downwardly and forwardly inclined draining batlie 27, which traverses the hood from one side of the same to the other. Located adjacent the center of the draining battle 27 is a baflle 27 which is inclined downwardly and forwardly at a considerably steeper angle than that of the draining baflie 27 The baflle 27 also extends across the hood. Located at the rear of the baffle 27 is a narrow baffle 28 which is downwardly and rearwardly inclined, and extends across the hood immediately beneath the top of the latter. At the rear end of thehood, a transversely-extending curved plate 29 is secured to the top and rear wall of the hood.

lVhen a car is traveling at high speed through the rain, the latter tends to blow directly, and almost horizontally, into the mouth of the hood. ing the hood strikes the baffles 26, and is deflected thereby downward against the draining baffle 27. Any moisture which maybe carried farther, by reason of the strong rush of air into the hood, strikes the battle 27 and is thereby deflected upward against the baffle 28, wherefrom it drops again onto the the upper part of the draining baffle 27. Thus all the moisture is directed onto the draining baffle 27, from which it drains onto the ledge 13, and thence off upon the roof of the car. The curved plate 29 directs downward, through the hatch-way, the currents of air which are directed by the baffle plates upward against the top of the hood.

The ice-plug includes a plug-portion 30 of a size and shape to fit snugly inthe tapered opening 12 and rest upon the seating-portion 15 of the cap. The plug por- Any rain thus entertion 30 is formed of suitable heat-insulating materials and is provided with a pair of bearings 31 secured to its upper face Hinged arms .32 have their forward ends hingedly connected with the bearings 31, and their rear ends rockably mounted on the rod 20 supported in the brackets 21. Thus the plug portion may be swung, by means of the hinge arms 32, up out of en gagement with the opening 12. This swinging movement may be effected either together with the ventilator hood (both parts hinging about the same axis), or independently thereof.

To permit of the opening and closing of the ice-plug independently of the ventilator hood, the plug-portion 30 is provided, at its rear end, with a stirrup 33, in which ongages the end 31 of a crank arm 35, which latter forms part of a stud 37 which extends through the rear wall of the ventilator hood and is rotatably mounted in the same, such wall being reinforced by a plate 36 at the point where the stud passes therethrough. The stud 37 has secured thereto, outside the hood, a handle 38, by'means of which the crank arm 35 may be rotated in one direction or the other. Vith the partsv in the position shown in full lines in Fig. 2,. it will be seen that if the crank arm 35 is rotated in a clockwise direction its end 31 will engage the stirrup 33 and thereby raise the plug portion 30 into the position shown in broken lines in the figure. Rotating the crank arm in theopposite direction will, of course, permit the plug-portion to re sun-1e its seating position in the opening 12.

The handle 38 has extending inwardly wall of the hood, when the handle 38 is in the position in which the plug-portion 30 is closed. vVhen the handle 38 is in the position in which the plug-portion 30 is open, the hasp 39 cooperates with a staple 41, which is likewise secured to the rear wall of the ventilator hood. By means of padlocks, car-seals, or the like, the hasp 39 may be locked to either one of the staples 40 and ll, and the plug-portion 30 thereby locked in either its open or closed position.

In use, two of thedevices are usually provided at each end of the car, one on each side of the center thereof. Each of the devices is disposed with its open part facing toward the center of the car. Thus the device at the rear end of the car will take in air (when the plug-portion is open),and

dirt are caught by the screen 25 and thus prevented from reaching the interlor of the car. Likewise, rain is caught by the bafiies 26, 27, 27 and 28 and permitted to drain ofi' either in the position, relatively to the hood,

shown'in Fig. 1, or it may be in the position relatively to the hood, shown in the dotted lines of Fig. 2; in the latter position, the plug is out of the way, and does not interfere with icing, etc. The plug-portion can likewise be closed with the ventilator hood, as a unit. .It will be seen that the device is very easily changed from the requisite position for icing to the requisite position for ventilation, and that it may be readily locked or sealed in any one of its positions. The device is of simple construction and there are no parts which are liable to get out of order during use. The construction is such that, in case of accident, any damaged parts may readily be repaired.

Having thus fully described my invention what I claim as new, and desire to secure by Letters Patent, is:

1. The combination with a car having a hatch-opening in the roof thereof, of a ventilator associated with said hatch-opening and covering the same, said ventilator including a hood portion having an opening at the forward end thereof, a plurality of downwardly and rearwardly inclined bafiies in said opening, a downwardly and forwardly inclined baflie mounted in said hood portion directed toward the opening, and adown- 1 wardly and rearwardly inclined bafile at the end of said hood remote from said opening, thereby to deflect the air currents downward through said hatch-opening.
